To determine if 2021 is a prime number or a composite number, we simply look at the factors for 2021.
If the factors of 2021 are only 2021 and 1, then we know that 2021 is a prime number. Otherwise, 2021 is a composite number.
To explain better, if 2021 is only divisible by 1 and 2021, then it is a prime number, and if 2021 is divisible by more than 2021 and 1, then it is a composite number.
The factors of 2021 are as follows:
1, 43, 47, 2021
Therefore, since 2021 is divisible by more than one and itself, the answer to the
question "Is 2021 prime or composite?" is highlighted in blue below.
composite
Is 2022 prime or composite?
OK. Now you know that 2021 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
